London Wall - Later Use and Remains

Later Use and Remains

The wall remained in active use as a fortification for over 1,000 years afterwards. It was used to defend London against raiding Saxons in 457, and was redeveloped in the medieval period with the addition of crenellations, more gates and further bastions. It was not until as late as the 18th and 19th centuries that the wall underwent substantial demolition, though even then large portions of it survived by being incorporated into other structures. Amid the devastation of the Blitz, some of the tallest ruins in the bomb-damaged City were remnants of the Roman wall.

The wall's moat has also left its mark on London; it forms the line of the street of Houndsditch. This was once London's main rubbish disposal site and was notorious for its appalling odour; its name, according to the 16th century historian John Stow, was derived "from that in old time, when the same lay open, much filth (conveyed forth of the City) especially dead dogges were there laid or cast." The moat was finally covered over and filled in at the end of the 16th century, becoming the present street.

During the Great Fire of London in September 1666, almost all of the medieval City of London inside the wall was destroyed.

Today all that remains of the wall are a few (albeit substantial) fragments, some of which can be seen in the grounds of the Museum of London, in the Barbican Estate and around Tower Hill. A section near the Museum of London was revealed at Noble Street, after the devastation of an air raid on 29 December 1940 at the height of the Blitz. Another visible section is at St Alphage Gardens, and other sections form part of the walls or foundations of modern buildings and are only visible from inside those buildings. One of the largest and most readily accessed fragments of the wall stands just outside Tower Hill tube station, with a replica statue of the Emperor Trajan standing in front of it.

In 1984 the Museum of London set up a Wall Walk from the Tower of London to the Museum, using 23 tiled panels. A number of these have been destroyed in subsequent years. At Noble Street, the panels were replaced by etched glass panels. These were intended as a prototype for new panels along the entire walk, but no further replacements have been made.
